ELECTRICAL SYSTEM
Owners of the 2018 Audi A5 report issues with the electrical system, specifically citing problems with the MMI system and the coolant pump. Complaints frequently mention the MMI screen rebooting every five minutes, including during the use of CarPlay. Additionally, some owners describe the vehicle entering limp mode due to electrical malfunctions related to the coolant pump, which a mechanic attributes to the pump's electrical component causing voltage dips. This issue is reported at approximately 87,000 miles and could potentially lead to overheating and fire risk if unresolved. These electrical problems may impact vehicle safety and usability, particularly for those considering purchasing a used model.
Owner complaints2
ENGINE
Owners of the 2018 Audi A5 report two main engine-related issues. One common complaint involves the failure of the oil cooler at around 36,000 miles, which leads to coolant mixing with engine oil and poses a risk of engine damage. Another issue described is the engine shutting off unexpectedly while cornering at low speeds, with no warning signs, and this has been occurring over several years. These issues highlight potential safety concerns, especially with the engine shutting off during driving, which may lead to loss of control. Used car buyers should be aware of these reported problems, particularly if the vehicle has similar mileage or usage patterns.
